Abstract

We employ a new version of the ABC macro-epidemiological agent based model presented in Delli Gatti and Reissl (2020) to evaluate the effects of vaccinations and variants on the epidemic and macroeconomic outlook. Vaccination plays the role of a mitigating factor, reducing the frequency and the amplitude of contagion waves, while also significantly improving macroeconomic performance. The emergence of a variant, on the other hand, plays the role of an accelerating factor, increasing the volatility of epidemic curves and worsening the macroeconomic outlook. If a more contagious variant emerges after vaccination becomes available, therefore, the mitigating factor of the latter is at least partially offset by the former. A new and improved vaccine in turn can redress the situation. Vaccinations and variants, therefore, can be conceived of as drivers of an intertwined cycle impacting both epidemiological and macroeconomic developments.
